Hi,
I am trying to do the following: the app has three "screens", they are all unrelated to each other, but user should be able to switch among them.
I use XTP's ShortcutBar to let the user switch views. I dynamically create coresponding views and it works so far so good. The only problem I have is the ReportControl's GroupBy feature. The question: How can I know the current state of ReportControl's GroupBy and how can I programatically restore its state when users needs to look at the view containing Report cOntrol.
Thank you in advance,
Rouslan.

Hi Rouslan,
Look into the Report Control sample app, method CReportSampleView::OnAutoGrouping(). You can use the similar approach to work with GroupBy items.
1) Saving: iterate all GroupOrder items and save an array of item indexes;
2) Restore the array by adding corresponding columns into the Group Order.
// saving
int nCount = GetReportCtrl().GetColumns()->GetGroupsOrder()->GetCou nt();
// iterate and save each Item Index: GetReportCtrl().GetColumns()->GetGroupsOrder()->GetAt( i)->GetItemIndex();
// restoring: iterate saved Item Indexes array:
CXTPReportColumn* pColumn = GetReportCtrl().GetColumns()->Find(SavedIndex(i));
GetReportCtrl().GetColumns()->GetGroupsOrder()->Add(pC olumn);
